Does Web Bluetooth work in Safari?

Yes — with the WebBLE Safari extension installed, navigator.bluetooth works in Safari on iPhone and iPad. The extension uses SafariWebExtensionHandler with full CoreBluetooth access to bridge the Web Bluetooth API. Install from the App Store and enable in Safari settings. Your existing Web Bluetooth code works unchanged.

How do I use Bluetooth in a web app on iPhone?

Install the WebBLE Safari extension, then use the standard Web Bluetooth API (navigator.bluetooth.requestDevice) or the @ios-web-bluetooth/core npm package for a simpler API. One line of code: import '@ios-web-bluetooth/core/auto' — this polyfills navigator.bluetooth on Safari iOS and is a no-op on Chrome/Edge where it's already supported.

Can Safari extensions access Bluetooth?

Yes. Safari Web Extensions on iOS use SafariWebExtensionHandler, which runs as a native iOS process with full access to CoreBluetooth. This allows the extension to scan for, connect to, and communicate with BLE devices, then relay data to web pages via the extension messaging API.

How It Works

Three steps to Bluetooth

Get started in under a minute. No configuration, no server-side changes.

1

Add one line

Drop a single script tag into your HTML. That's the entire integration.

<script src="https://ioswebble.com/webble.js"></script>

2

User enables the extension

On first visit, users install the free companion app and enable WebBLE in Settings > Apps > Safari > Extensions.

3

Bluetooth just works

The standard Web Bluetooth API is now available. Your existing code works without changes.

For Developers

Integrate in seconds

Use the standard Web Bluetooth API. We handle the Safari part.

<script src="https://ioswebble.com/webble.js"></script> // Then use the standard Web Bluetooth API const device = await navigator.bluetooth .requestDevice({ acceptAllDevices: true, optionalServices: ['battery_service'] }); const server = await device.gatt.connect();

Standard API. Zero lock-in.

WebBLE polyfills the Web Bluetooth API for Safari. If the user has Chrome or Android with native support, the polyfill stays out of the way. Your code is always standard.

Works with every framework, or no framework at all.
